Stable vices including weaving, crib-biting, and box walking are stereotypic behaviors that indicate chronic welfare problems arising from inappropriate housing and management.
Equine stereotypies are welfare indicators — their presence reflects historical or ongoing environmental deficiencies including inadequate social contact, forage access, and movement opportunity. Anti-cribbing collars and physical barriers address the symptom while ignoring the underlying welfare issue. Horses displaying stereotypies require environmental improvement including increased turnout, social housing, and ad libitum forage access. Managing rather than punishing stereotypies is the welfare-appropriate approach.
